* PAGE_ALIGN(): correctly handle 64-bit values on 32-bit architecturesAndrea Righi2008-07-24
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | On 32-bit architectures PAGE_ALIGN() truncates 64-bit values to the 32-bit boundary. For example: u64 val = PAGE_ALIGN(size); always returns a value < 4GB even if size is greater than 4GB. The problem resides in PAGE_MASK definition (from include/asm-x86/page.h for example): #define PAGE_SHIFT 12 #define PAGE_SIZE (_AC(1,UL) << PAGE_SHIFT) #define PAGE_MASK (~(PAGE_SIZE-1)) ... #define PAGE_ALIGN(addr) (((addr)+PAGE_SIZE-1)&PAGE_MASK) The "~" is performed on a 32-bit value, so everything in "and" with PAGE_MASK greater than 4GB will be truncated to the 32-bit boundary. Using the ALIGN() macro seems to be the right way, because it uses typeof(addr) for the mask. Also move the PAGE_ALIGN() definitions out of include/asm-*/page.h in include/linux/mm.h.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | Remove the DB1200 board-specific functions (card present, read-only, activity LED methods) and instead add platform data which is passed to the driver. This also allows for platforms to implement other carddetect schemes (e.g. dedicated irq) without having to pollute the driver code. The poll timer (used for pb1200) is kept for compatibility. With the board-specific stuff gone, the driver's ->probe() code can be cleaned up considerably.

[Ralf: The bug was actually intensional. Some versions used to throw an error under certain circumstances for code like: static inline void f(unsigned nr, unsigned *p) { unsigned short bit = nr & 5; if (__builtin_constant_p(bit)) { __asm__ __volatile__ (" foo %0, %1" : "=m" (*p) : "i" (bit)); } else { /* Do something else. */ } } because gcc was not able to figure out that the "i" constraint was possibly at the early stage when the constraint are getting verified. The solution was using "ri" instead of "i". The "ri" would keep gcc happy but in the end for code generation always the "i" constraint would be satisfied. The problem afair originally appeared in the i386 io.h and also hit it's mips equivalent. From there the workaround spread to many of the inline assembler functions.] Signed-off-by: David Daney <ddaney@avtrex.com> Signed-off-by: Ralf Baechle <ralf@linux-mips.org>
